What export based on the driving of gas pressure source miniflow pump connects stock-solution pipe soonTechnical field
The present invention relates towhat export based on the driving of gas pressure source miniflow pump connects stock-solution pipe soon.May be used for being plugged on gas pressure source miniflow pump drives on the quick-acting joint of outlet, realizes connecing soon manipulating reagent easily.
Background technique
Miniflow pump driving arrangement, as a kind of device providing power, is mainly used in driving the movement of small volume reagent in micro channel, the running of manipulation reagent on minute yardstick platform, mixing, assembling, the various biochemical reaction of generation.The constant voltage miniflow pump driven based on gas pressure source adopts gas as power source and working medium, drives reagent.Traditional miniflow pumping unit is contained in by reagent in built-in special container chamber, inserts output tube, install sealing cover, then manipulate.This handling mode seems more clumsy, easily causes reagent contamination miniflow pump box body when adding reagent or placing stock-solution pipe, especially when manipulating parallel multi-channel, being difficult to realize freely to increase multiple joint and carrying out single source of the gas and manipulate simultaneously.
Quick union, can quick mounting and dismounting as a kind of assembling pipe joint, and possesses good tightness, is mainly used in pipeline and connects, as pipeline fluid conveying node.In process engineering, in industrial production, there is good application.Such as Chinese invention patent application (application number: 201410578210.9; Authorize publication number: CN 104329527 A) disclose a kind of straight-through quick union, its field relates to pipe joint field, easy installation and removal can be realized, good sealing effect, the effects such as structure is simple, but quick union is generally used as the node of stream, only directly flow to outflow for what realize liquid, liquid conveying device based on quick access device and stock-solution pipe are seldom used in micro passage especially miniflow pump driving arrangement.
Summary of the invention
technical problem:the invention provides drive outlet based on gas pressure source miniflow pump connect stock-solution pipe soon, when can be implemented in that fast peace connects stock-solution pipe, the mouth of pipe on adapter head and quick union (figure mono-) are in place simultaneously.
technological scheme:technological scheme of the present invention comprises stock-solution pipe, the described stock-solution pipe mouth of pipe is provided with adapter head 3, described adapter head 3 center is provided with cylindrical tube pipeline connector 7, is provided with several air vents 4 around described cylindrical tube pipeline connector 7, and described cylindrical tube pipeline connector 7 lower end is connected to fluid tubule 10; When stock-solution pipe inserts the quick union of gas pressure source miniflow pump discharge, described cylindrical tube pipeline connector 7 and the inner connecting tube mouth closed butt joint in described quick union.
Described adapter head 3 is the cylinder of two joint different-diameters, and lower pitch cylinder diameter is suitable with stock-solution pipe 5 internal diameter, can insert stock-solution pipe 5; Upper pitch cylinder diameter is suitable with stock-solution pipe 5 external diameter, with stock-solution pipe 5 interference fit.
Described air vent 4 number is 4, is uniformly distributed around described cylindrical tube pipeline connector 7.
Described stock-solution pipe 5 outer wall is provided with the elastic seal ring 6 and Baltimore groove 8 that match with quick union inwall; The projection 9 for propping up quick union bottom is provided with at Baltimore groove 8 lower position.
Also comprise pipe cap 11, described pipe cap 11 is enclosed within described adapter head 3.
Compared with prior art, beneficial effect of the present invention has:
1) adapter head and stock-solution pipe assemble to be formed and integratedly connect stock-solution pipe soon, are convenient to encapsulation, point deposit various reagent;
2) closed butt joint realizing pipe joint in adapter head and quick union closure member inner spout when stock-solution pipe inserts piecing devices is connect soon, convenient and swift;
3) adapter head and stock-solution pipe are special, can be used as disposable object, avoid cleaning, effectively can prevent reagent contamination;
4) accessory is easy for installation, simple to operate, safe and reliable.

Embodiment
Now the present invention is described in further detail in conjunction with the accompanying drawings and embodiments.
As shown in Figure 1,2 and 3, the present invention is mainly divided into two pieces, i.e. adapter head 3 and stock-solution pipe 5.Adapter head 3 with air vent 4, cylindrical tube pipeline connector 7 and fluid tubule 10, air vent 4 is evenly distributed on around cylindrical tube pipeline connector 7, and number is 4; Liquid storage tubule 10 is connected with cylindrical tube pipeline connector 7.Stock-solution pipe 5 outer surface is embedded with elastic seal ring 6, Baltimore groove 8 and protruding 9.
Adapter head 3 is cylindric, is divided into joint and lower joint, respectively with different diameters.Lower joint diameter is suitable with stock-solution pipe internal diameter, upper joint diameter is suitable with stock-solution pipe 5 external diameter, during lower joint partial insertion stock-solution pipe, upper joint part is stuck in the mouth of pipe, with stock-solution pipe interference fit, stock-solution pipe 5 can be inserted by spacing adapter head 3, support when simultaneously coordinating with the cylindrical inner connecting tube mouth 2 in quick union closure member 1 as the cylindrical tube pipeline connector 7 in adapter head 3.Be interspersed with cylindrical tube pipeline connector in the middle of adapter head, the lower end of pipe joint is connected with fluid tubule, is drilled with four cylindrical airway, stock-solution pipe is communicated with pump steam inlet around joint.Stock-solution pipe profile is similar to standard eppendorf pipe.
During concrete use, stock-solution pipe 5 is installed reagent, clog with adapter head 3.Press the locking plate pushing surface 12 of quick union, the stock-solution pipe 5 assembling adapter head 3 is inserted quick union, until projection 9 props up the bottom of quick union, realize self-locking, as shown in Figure 4.Now, the cylindrical tube pipeline connector 7 in adapter head 3 is also complete with cylindrical inner connecting tube mouth 2 attaching in quick union closure member 1.Open the switch air inlet of miniflow pump, can reagent be manipulated.
Described projection 9 has position-limiting action, and when propping up quick union, stock-solution pipe is lockable just, and cylindrical tube pipeline connector 7 also coordinates completely with cylindrical inner connecting tube mouth 2 simultaneously.
The stock-solution pipe that connects soon based on gas pressure source miniflow pump discharge of the present invention also comprises pipe cap 11, and pipe cap 11 can be set in the mouth of pipe of stock-solution pipe 5, realizes the hermetically sealed of stock-solution pipe 5, uses as the common stock-solution pipe holding reagent.In use, multiple stock-solution pipe can being prepared, depositing various different reagent, to realize different actual demands for dividing.
Adapter head 3 of the present invention is special with stock-solution pipe 5, makes simple, easy for installation, can be used as disposable object, avoid cleaning, effectively prevent reagent contamination.
The above is only the preferred embodiment of the present invention, protection scope of the present invention be not only confined to above-described embodiment, and all technological schemes belonged under thinking of the present invention all belong to protection scope of the present invention.It should be pointed out that for those skilled in the art, without departing from the principles of the present invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
